Water has a specific heat of 4.186 J/g°C. How much heat is required to increase 10.0 g of water from 25.0°C to 30.0°C?

Respuesta :

Mass times specific heat capacity times change in temperature = energy required to raise the temperature in this case

10x4.186x(30-25)=209.3 J

Answer: 209.3 J

Explanation:

The heat required to increase the temperature of a substance is given by

[tex]Q=mC_s \Delta T[/tex]

where

m is the mass of the substance

[tex]C_s[/tex] is the specific heat capacity of the substance

[tex]\Delta T[/tex] is the increase in temperature of the substance

In this problem, we have:

[tex]m=10.0 g[/tex]

[tex]C_s = 4.186 J/gC[/tex]

[tex]\Delta T=30.0 C-25.0 C=5.0 C[/tex]

Substituting into the equation above, we find

[tex]Q=(10.0 g)(4.186 J/gC)(5.0 C)=209.3 J[/tex]
